Electronic Voice Phenomena (E.V.P.) to most people sounds like nothing more than electronically generated noise or speech, for which very close attention needs to be given while listening for EVPs, let alone identifying one correctly. These recordings are still considered to be the best evidence for the paranormal investigator, as they are not the result of input or rendering. Commonly associated with ‘white noise’ (a noise produced by a stimulus containing all of the audible frequencies of vibration; "while white noise can be a good masking agent" it is also a the bandwidth in which EVPs often reside) it is the most common source for E.V.P.s that can include static, stray radio transmissions, and background noise. Interest in the subject normally surrounds claims that E.V.P.s are of paranormal origin, yet the only part of the EVP that is, is the white noise generated from the residual energy of the ‘Big Bang.” Although there can often be natural explanations for the EVP such as apophenia (the experience of seeing patterns or connections in random or meaningless data where none exists), and a form of auditory pareidolia (where the brain incorrectly interprets what seems to be patterns of sound; speech, voices, music, slamming, knocking, and footsteps). The equipment is usually not a fault, however, they can produce a simple hoax which can be  offered as a means to explain them. Recordings of E.V.P. are often created from background sound by increasing the gain (i.e. sensitivity) of the recording equipment. It is also not uncommon to find EVPs in an auditory frequency outside the range for humans to detect (12 Hz under ideal laboratory conditions to 20,000 Hz), and can be heard only when that frequency is adjusted with the aid of electronic equipment. Of course that frequency range narrows with age. Determining the Relevance of an EVP In an effort not to bore you with the AA-EVP classifications that have been used for many years and originally developed by the late Sarah Estep in 1983. We will simply say that they are very confusing to understand let alone document. For that reason many paranormal investigators have begun to adopt a much simpler methodology to classify the EVP evidence by relevance. Adopted in 2007.
